Slimtox (Australia) Pty Ltd v Slim By Nature Pty Ltd

This decision concerns cross-oppositions between Slimtox (Australia) Pty Ltd and Slim By Nature Pty Ltd, both operating in the weight-loss sector, regarding the trade mark DETOX26. Slim By Nature filed two applications for the trade mark, which were opposed by Slimtox. Conversely, Slimtox applied for the same trade mark, and this application was opposed by Slim By Nature. The delegate of the Registrar of Trade Marks was tasked with determining the validity of these oppositions.

The primary legal issues before the delegate were whether the applicants were the rightful owners of the trade mark DETOX26, and whether the trade mark should be refused registration on various grounds, including those relating to ownership, reputation of other trade marks, and deceptive or misleading conduct. Specifically, the delegate had to consider oppositions under sections 58, 42(b), 60, and 62A of the *Trade Marks Act 1995* (Cth).

The delegate's reasoning focused significantly on the concept of ownership under section 58 of the Act. Applying established legal principles, the delegate determined that ownership of a trade mark is generally vested in the first person to use it in the course of trade in Australia, particularly when both parties claim prior use. The delegate found that Slim By Nature had provided sufficient evidence of using the DETOX26 trade mark in relation to goods and services, including "Detox Support Drops" and a 26-day "Body Slimming Detox" program, as early as September and October 2016. This predated Slimtox's claimed use and application date. Consequently, Slim By Nature was deemed the owner of the trade mark for the relevant goods and services.

Based on this finding of ownership, the delegate ordered that Slimtox's opposition to Slim By Nature's trade mark application 1835887 be successful, and the trade mark be refused registration. However, Slimtox's oppositions to Slim By Nature's applications 1835881 and 1835882 were unsuccessful, as the delegate found no grounds established under sections 42(b), 58, 60, or 62A. Therefore, these applications were permitted to proceed to registration.
